Answers to common questions, and how to reach us.
Frequently asked questions
Does it work with USB drives and network shares?
Yes, with anything Windows shows as a folder. For FAT/exFAT drives and memory cards there is a time tolerance and the option “ignore 1-hour offset” for daylight saving time.
Does two-way sync detect deleted files?
No, on purpose. Without a stored previous state that would be guesswork. Use “Mirror” when deletions should be carried over; it is always previewed and backed up.
Can I undo a sync?
Yes. Replaced and removed files are backed up first, and the last sync can be rolled back from the history.
How are files compared?
By size and date (fast) or byte by byte (certain). You can include only certain types such as *.jpg; *.docx, or exclude patterns such as node_modules; .git; *.tmp.
Does Folvane send data to the internet?
No. The app has no network access for your data, no account and no telemetry. See the privacy page.
Is there a subscription?
No. It is a one-time purchase.
Keyboard shortcuts
F5 compare · Ctrl+O choose left folder · Ctrl+Shift+O choose right folder · Ctrl+F search · Ctrl+E report · F8 next change in the text diff.
Where are my backups?
Backups of a sync are stored in the hidden .folvane-backup folder inside the affected folder. Use “History” in the app to undo a sync instead of restoring files by hand.
Command line
Run folvane <left> <right> to compare two folders, or folvane --profile "Name" to open a saved profile.
